Tettigoniid genus JZphippithyta, although in that genus, so 

 far as known to me, there are no spots in the costal field.

? . Length, exclusive of ovipositor, 33 mm ; with ovipositor 

 about 40 ; ovipositor strongly curved, its length along the 

 curve slightly over 10 mm ; length of head from vertex to apex 

 of mandibles about 6 mm ; length of prothorax 4-| min . Tegmina 

 and wings ample, the tegmina incomplete, but length about 

 38 lum ; their markings consisting of fine transverse more or 

 less broken reddish-brown bands producing a mottled effect; 

 venation not well preserved, but essentially as in Gryllaeris, 

 the costal and subcostal veins each with strong oblique upper 

 branches, the subcostal connected with the radius by straight 

 transverse veins, the radius with strong oblique branches 

 below.

 Ro/iwe?*). This is considerably larger than G. cineris Scuclder. 

 from Florissant, and is readily distinguished by the markings of 

 the tegmina. Scudder remarks that G. cineris, as well as the 

 European Tertiary species of Gryllaeris, belong to the. genus 

 in a broad sense, and this is equally true of G. mutilata. It is 

 more than likely that if these insects were perfectly preserved 

 they could some of them be made the types of new genera ; but
